  9. Soekris discrete R2R DAC?

    Pardon my ignorance but what's the difference between this Belkin one and the ones on eBay that sells for a fraction of its price?

    Most likely none. There’s a small chance that some come with non-working drivers, so if you are unlucky and get a bad one, then just order another :)

    I think it depends on your preferred tonality balance. For me, the 009>>L700>>007mkII progression tilts the perception curve toward more bass and less treble.

    I think you're coming from the 507? If so, the 007mkII will likely sound most different from what you have now (but still great, I use those more than my 009's out of my Carbon).

    I am using  a GRLV to supply around 1A current per rail for my DAC but it's only running 15VDC rails and it has not blown up yet... 

    So, presumably 1.5A per GRLV then (i.e. 3.0A for a bipolar one).

    That said, Sören’s suggestion above is very interesting! I’ll think about rebuilding my Dynahi Psu that way, just to try it out.

    The + rail and - rail draw the same current.

    So around 2A in total (pos and neg rail combined)? If I remember correctly, Dynahi pulls about 2.4A in total (600mA per rail per board), so you'll be close to Dynahi levels with your next step

    Btw, can GRLV deliver that much current? I thought it maxed out at 1.5A, but maybe that was per rail, not total?

  21. K1000 successor Mysphere?

    @mdr30 arranged for a prototype to pass by Gothenburg for evaluation a few months ago. Transient response was very good but the frequency voicing was quite off; at that time they claimed to have voiced it for vocals which translated into a big upper mid hump that made it difficult to listen to. Mid-bass was also lacking. They claimed they would address that right away; apparently we were not alone in giving this feedback... 

    They do however give a whole new meaning to the concept of open headphones :) Very different, but in a good way. At HD-800 price levels, it would be a contender. At 4K, not so much I think.

  22. current feedback electrostatic amp

    I agree. Built a 360-ish volt version before, so will do a 400V next time. 

    For the record, as good as Dynahi and Dynalo are, the CFA2 is where I plug my dynamic cans in most often. Guess I have a personal preference for current feedback.

    Or perhaps more adequately, Kevin's current feedback designs are awesome :)

    It is a great amp, fairly independent of price range I think (though 37K obviously is the Best Ever...)

    When I build mine, I only had it for a couple of weeks and really liked it a lot. Then a friend asked to borrow an e-stat setup so it went to him for further opinion. A month later he declared he’s not giving it back unless I force him to do so. Have to build another one I guess :)

  24. The Headcase Stax thread

    Well, just checked mine and they are SZ2 - 2253.

    I purchased them on site in Tokyo in November last year from a music store. They were not in stock at the store, so these were delivered straight from Stax the next day.

    Unless someone kept yours in storage for a couple of years before selling, I'd assume it's new stock.
